Specification of Letters Patent.

Patented Sept. 25-, 1917.

Application filedNovember 6, 1916. Serial No. 129,807.

To all whom it may concern:

Be it known that I,-l/VILLIAM L. SMITH, a citizen of the United States, residing at Wheatland, in the county of Cass, State of North Dakota, have invented certain new and useful Improvements in Lamp-Supporting Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in brackets, and particularly to lamp supporting brackets.

One object of the invention is to provide a supporting bracket for a lamp which can be attached to the wall and extended therefrom for supporting a lamp, or can be placed on the floor or table or suspended from the ceiling.

Another object is to provide a lamp bracket' which is extensible and includes means for holding the bracket in such extended position. Y

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure l is a side elevation of my improved lamp bracket showing the same attached to the wall and in extended position,

Fig. 2 is an elevation of the device in the position assumed when resting on the floor or table,

Fig. 3 is a top plan view of the outer end of the bracket in the position of Fig. 1,

Fig. 4 is a transverse section on the line 4.& of Fig. 3,

Fig. 5 is a transverse section on the line 55 of Fig. 4, and

Fig. 6 is an enlarged vertical section on the line 66 of Fig. 3.

Referring particularly to the accompanying drawing, 10 represents a bar which is secured in a horizontal position to a wall. The upper end of this bar has an outwardly and upwardly turned portion 12 and a lower straight outturned portion 13, the purpose of which will be referred to later. An

open-work frame 14 has a plurality of V- shaped portions 15 formed in the inner side thereof, these portions being arranged in diametrically opposite pairs. The frame is placed over the bar 10, against the Wall .so that the projection 12 will engage in two diametrically opposite V-shaped portions. Thus, the frame is held in supported position on the wall and by means of the projections is prevented from any rocking movement. Secured in the frame and extending at right angles to the bar 10 is a transverse rod 16 on which rod there are slidably mounted the sleeves 17 and 18. Pivotally connected to these sleeves are the lowermost links 19 of the lazy tongs 20. Pivotally connected to the outermost links 21 are the short links 22, their other ends being connected to a pair of vertical bars 23 which straddle the pivotal connection of the upper links 21, these bars having slots 2& which receive the clamping screw 25 which forms the pivot of the said links 21. Thus when the lazy tongs are extended they can be held in such extended position by tightening the clamping screw 25. The upper ends of the links 22 are pivotally connected between the bars 23 by means of a second clamping screw 26.

The upper ends of these bars 23 are turned outwardly in opposite directions and are secured to the horizontal portion of a U-shaped yoke 27. Disposed between the upper ends of the arms of this yoke is a horizontally disposed band 28 one side of which is pivotally connected to the adjacent arm by a bolt or rivet 29. The opposite arm carries an arcuate plate 30 in which are formed a plurality of openings 31. Ascrew 32 is passed through this arm, through the plate and into the band. A set screw 33 is carried by the arm below the screw 32 and is arranged to be screwed inwardly to engage in any one of the openings 31, thus providing means whereby the band 28 can be rotated on the pivots 29 and 32 and clamped in different positions. The ends of the band are adjustable by means of the pin 34 carried by one end of the band for engagement in openings 35 formed in the other end of the band. This band is adapted to be clamped around the bowl or font of a lamp, the bottom of the lamp resting on the transverse portion of the yoke 27 when the bracket is incan uprightposition, but which will swing clear when the bracket is extended out from the wall.

Carried by the frame 14 adjacent the sleeve 18 is a ratchet segment 36 which is arranged to be engaged by a pawl 37 carried by a lever 38 formed on the sleeve 1.8.

By means of this lever the lazy tongs can be swung on the shaft 16 and held in such different positions by means of the pawl and ratchet segment.

What is claimed is:

A lamp support including a base member, an adjustable arm carried by the base memher, and a lamp retaining means on the outer end of the arm consisting of a yoke,

an adjustable lamp encircling ring pivotally mounted on one arm of the yoke, an arcuate plate carried by the pivoted portion of the ring said plate being formed with a plurality of openings arranged in a circular line concentrically with the pivot of the ring, a clamping screw carried by the other arm of the yoke for binding engagement with the adjacent side of the ring, and a set screw carried by the first-named arm of the yoke for interchangeable engagement in the openings of said plate.

In testimony whereof. I aflix my signature, in the presence of two witnesses.
